ABSTRACT A wire stitcher for binding sets of sheets has a driver for driving a staple through a set and an active clincher for bending over the ends of the staple legs to form clinches. The clincher includes an ear 204 having a first groove 215a in a side edge 215 for catching the end of a driven staple leg and initiating bending of the leg and a second, narrower groove 216a in an end edge 216, which is contiguous with the groove 215a and aligns the leg and completes the bending thereof. A transition groove portion 228 connects the grooves at the junction of the edges 215, 216.
